Tentukan rumus fungsi f(×) jika A. 3f(×)-2=3×+4 B.3-2f(×)=2×^2+6×-5 C. f(×)+3per4=2×+5 D. (f(×))^2-5=3×-4 Dengan caranya!

A. 3f(x)-2 = 3x+4
3f(x) = 3x+4+2
3f(x) = 3x+6
f(x) = (3x+6)/3
f(x) = x+2

B. 3-2f(x) = 2x^2 + 6x - 5
-2f(x) = 2x^2 + 6x - 5 - 3
-2f(x) = 2x^2 + 6x - 8
f(x) = (2x^2 + 6x - 8)/(-2)
f(x) = -x^2 - 3x + 4

C. f(x) + 3/4 = 2x + 5
f(x) = 2x + 5 - 3/4
f(x) = 2x + 20/4 - 3/4
f(x) = 2x + 17/4
f(x) = 2x + 4 1/4

D. f(x)^2 - 5 = 3x - 4
f(x)^2 = 3x - 4 + 5
f(x)^2 = 3x + 1
f(x) = akar (3x + 1)

Semoga bisa dipahami.
Jangan lupa mandi pagi.
